SURGERY TIKI TAKA ___________________

. TRAUMA:__________

__________(1) AIRWAY:

____________. Establishing & securing the airway is always the 1st step in management.. Altered mental status is the most common indication for intubation in a trauma pt.. As an unconscious pt can't maintain his airway.. The preferred method of securing an airway -> OROTRACHEAL INTUBATION.. Trauma with cervical spine injury -> FLEXIBLE BRONCHOSCPE.. Extensive facial trauma & bleeding into airway -> CRICOTHYROIDOTOMY or TRACHEOSTOMY.

. N.B.. Pts with cervical spine injury should 1st have stabilization of the cervicalspine.. Oro-tracheal intubation with rapid sequence intubation is the preferred way,. to secure an airway in an apnein pt with a cervical spine injury.

. N.B.. In burn victims, clinical indicators of thermal inhalation injury to the upper airway,. or smoke inhalation injury to the lungs include burns on face, singing of eyebrows,. oropharyngeal inflammation & blistering, oropharyngeal carbon deposits,

. carbonaceous sputum, stridor, carboxyhemoglobin level > 10 %.. H/O of confinement in a burnung buiding.. The presence of one or more of these indicators warrants early intubation,. to prevent upper airway obstruction by edema.

(2) BREATHING:_______________. Check oxygen saturation, if SpO2 < 90 %:-> ++ oxygen concentration & flow rate.-> Obtain an ABG.-> Determine the likely cause of hypoxia from H/O.

(3) CIRCULATION:_________________

* CHEST TRAUMA (Hypovolemic shock - Pericardial tamponade - Tension pneumothorax):______________________________________________________________________________________________________________________________________________________________________-> HYPOVOLEMIC SHOCK:

______________________

. The most common type of shock.. Pale, cold , shivering pt with diaphoresis, hypotension & tachycardia.. Look for a source of bleeding.


2/50

. The pt may lose a large volume of blood in the abdomen or thigh following femur #.

. N.B.. When hemorrhage occurs, tachycardia & peripheral vasoconstriction are the 1stchanges.. These responses act to maintain the blood pressure within normal limits.

. PULSE CHANGE IS THE FIRST INDICATOR FOR HYPOVOLEMIA.-> Pericardial tamponade:

__________________________. Cause distended neck veins & high central venous pressure.. Enlarged heart on CXR (May be normal cardiac silhouette).. Electrical alternans on EKG.. Pulsus paradoxus on vital signs.. Tx -> immediate pericardiocentesis tap or pericardial window.

. N.B.. Acute cardiac tamponade:

. occurs due to a sudden rise in intra-pericardial pressure.. Should be suspected in all adult pts with blunt chest trauma.. Jugular venous distension, Tachycardia & Hypotension despite aggressive fluidresusc.. CXR findings typically reveal a normal cardiac silhouette without tension pneumothorax.

-> Tension pneumothorax:_________________________. Cause distended neck veins & high central venous pressure.. Respiratory distress, tracheal deviation, absent breath sounds.. Hyperresonance to percussion.. Tx -> immediate placing of a large-bore needle or IV catheter into the pleura

l space.. Chest tube placement.. Never wait for a CXR for diagnosis.

. N.B.. Don't be distracted by head trauma or dilated pupils in a hypotensive traumapt.. Intracranial bleeds are never the cause of hypotensive shock.. The 1st step in management is to identify & control the site of bleeding.

. N.B.. Most causes of shock in the setting of trauma are 2ry to hypovolemia from blo

od loss.. However, ++ CVP/PCWP or failure of hypotension to resolve after a bolus of IVfluids,. should suggest an alternative diagnosis.. Myocardial contusion sh'd be suspected in pts with evidence of injury to anterior chest. MI can be confirmed with +ve cardiac markers & EKG changes.. Tension pneumothorax is excluded if there is no tracheal deviation.

. Hypovolemia is excluded if there is failure to respond to an IV fluid bolus.

. N.B.

. High energy blunt trauma to the chest commonly causes aortic injury.. In most cases of aortic rupture, death is the immediate result.. Widened mediatinum, large left sided hemothorax & mediastinal deviation to ri


3/50

ght side.. Disruption of the normal aortic contour... Bilateral COLLAPSED neck veins.

. Cardiac contusion & rupture cause pericardial tamponade only.. Muffled heart sounds - Hypotension - DISTENDED NECK VEINS.

. N.B. PULMONARY CONTUSION:____________________________. Represents pulmonary bruising of the lung.. Common after high-speed car accidents.. Clinical manifestations develop in the 1st 24 hours (Often within few minutes).. Tachypnea - Tachycardia - Hypoxia.. P/E -> Chest wall bruising & -- breath sounds on the side of pulmonary contusion.. CXR -> Patchy irregular alveolar infiltrate.. ABG -> Hypoxemia.

. It is very important to differentiate pulmonary contusuion from ARD$.. ARD$ manifests 24 - 48 hours from the trauma & BILATERAL involvement.. Pulmonary contusion manifests in the 1st 24 hours.

. N.B. PNEUMOTHORAX:. Primary spontaneous pneumothorax -> No preceiding event & No H/O of lung disease.. Secondary spontaneous pneumothorax -> Complication of underlying COPD.. Tx -> Small ( < 2cm between lung & chest wall on CXR) -> Observation & oxygen.. Tx -> Large (Stable) -> Needle aspiration or chest tube.

. Tension pneumothorax:

________________________. Life threatening; trapped air with mediastinal shift.. Compromised cardiopulmonary function.. Chest pain or dyspnea.. -- Breath sounds / -- TVF / -- chest movement.. Hyperresonance to percussion on the affected side.. Tachycardia, hypotension.. Tracheal deviation away from the affected side.. Imaging -> Notable visceral pleural line.. Imaging -> Air in hemithorax -> Contralateral mediastinal shift.. Imaging -> Radiolucent costophrenic sulcus.. Tx -> Urgent needle decompression then chest tube placement (Tube thoracostom

y).. Tx -> IV lines & fluid resuscitation follow urgent needle decompression.

. N.B.. ONLY TWO CAUSES OF DISTENDED NECK VEINS -> TENSION PNEUMOTHORAX & CARDIAC TAMPONADE.. N.B.. In HEMOTHORAX -> Neck veins are COLLAPSED !

. N.B. FLAIL CHEST:____________________

. Follows major thoracic trauma.. Multiple contigious ribs are fracutred in two or more locations.. Causing a segment of rins losing its continuity with the rest of thoracic wal


4/50

l.. The pt takes shallow breaths due to severe pain.. The pt compensates for the hypoxemia by hyperventillation.. Tachypnea & PARADOXICAL THORACIC WALL MOVEMENTS.. Paradox is corrected with positive pressure mechanical ventillation.. The isolated thoracic wall segment exhibits paradoxical motion,. inward motion on inspiration & outward motion during expiration !

. Tx -> Pain control & supplemental oxygen are the most important steps.. Positive pressure mechanical ventillation replaces the negative intrapleuralpressure.. so the flail chest movement will be normal with the rest of the rib cage on inspiration

. N.B. HEMO-THORAX:____________________. After blunt chest trauma, hemorrhagic shock associated e'. decreased breath sounds & dullness to percussion over one hemithorax.. & contralateral tracheal deviation.. COLLAPSED NECK VEINS.

. Most common cause is damage to intercostal or internal mmamary artery.

* ABDOMINAL TRAUMA:____________________. The 1st step in management is always to control the site of bleeding if known. -> Apply direct pressure when the site is visible (e.g. extremity). -> Blind clamping & the use of tourniquet is NEVER the answer.

. The next priority is FLUID RESUSCITATION.

. Do several things at once in preparation for immediate exploratory laparotomy:

-> Set up 2 large gauge IV lines. -> Give fluids & blood. -> Insert Foley catheter. -> Administer IV antibiotics.

. If surgery isn't needed (blunt trauma),. fluid resuscitation is the 1st step in management (Also diagnostic).. If the pt responds promptly, then he's propably no longer bleeding.

. N.B.. Intraosseous cannulation in the proximal tibia is used in children (generally< 6ys).

. Give an initial bolus of Ringer's lactate at 20 ml/kg of body weight.

. N.B. BLUNT ABDOMINAL TRAUMA (BAT):_____________________________________. After a car accident of a restrained driver.. Usually occurs when a lap belt (without shoulder attachment) compresses the abdomen,. and lacerates solid organs most commonly the spleen & liver.. Hypotension, tachycardia, facial lacerations & abdominal wall ecchymosis.. Most reliable symptoms -> Abdominal pain, tendrness & peritoneal signs.. Intraabdominal injury sh'd be suspected in pts with:. abdominal wall ecchymosis,abdominal distension & hyperactive bowel sounds.

. 1st step after fluid resuscitation to determine if the pt needs exploratory laparotomy.. All pts with BAT sh'd 1st be assessed for intraperitoneal free fluid or hemor


5/50

rhage.. Best test is -> BEDSIDE ULTRASONOGRAPHY to detect free intraperitoneal fluid,. in hepatorenal space, splenorenal recess & inferior portion of intraperitoneal cavity.. When combined with pericardial evaluation -> known as FAST.. FAST exam -> (Focused assessment with sonography for trauma).. It is the best to detect hemoperitoneum, pericardial effusion or intraperiton

eal fluid.. If FAST exam is limited or equivocal -> A diagnostic peritoneal lavage (DPL)is done.. DPL is done to evaluate for hemoperitoneum.

. Pts with +ve findings on either FAST or DPL -> should undergo exploratory laparotomy.

. Hemodynamically stable pts with -ve findings on FAST may undergo abdominal CT,. to determine need for laparotomy.

. Hemodynamically un-stable -> FAST or DPL.. N.B.. Blunt abdominal trauma to the upper abdomen can cause pancreatic contusion,. crush injury, laceration or transection to the pancreas.. Pancreatic injuries may be MISSED by CT scan during the 1st 6 hours followingtrauma.. Untreated pancreatic injury can be complicated by retroperitoneal abscess orpseudocyst. N.B.. The spleen is the most commonly injured organ following blunt abdominal traum

a.. Left upper quadrant abdominal pain.. Abdominal wall contusion, Lt lower chest wall tendrness.. Lt shoulder pain referred from splenic hemorrhage irritating phrenic nerve &diaphragm.. It is called "KEHR" sign.. Splenic rupture causes acute left upper quadrant abdominal pain.. Delayed hypotension may result due to blood loss.. No signs of sepsis will be present.. Dx -> Abdominal CT with IV contrast.

. N.B.

. Blunt deceleration trauma (Motor vehicle accident or fall from > 10 feet):. Blunt aortic trauma must be ruled out.. CXR is the initial screening test -> WIDENING of the mediastinum.

. N.B.. Duodenal hematoma:

_____________________. mostly follow abdominal blunt trauma in children.. The hematoma may cause duodenal obstruction with nausea & vomiting.. Epigastric pain & vomiting due to failure to pass gastric secretions past obstruction.. Tx -> NASOGASTRIC SUCTION & PARENTERAL NUTRITION.. Most hematomas will resolve spontaneously in 1-2 weeks.

. N.B.. Any gun shot wound below the 4th intercostal space (level of the nipple) is:


6/50

. considered to involve the abdomen & requires an exploratory laparotomy in unstable pts.

. N.B.. All hemodynamically UN-STABLE pts with penetrating abdominal trauma,. must undergo immediate exploratory laparotomy to diagnose & treat source of bleeding

. as well as to diagnose & treat perforation of any abdominal viscus to preventsepsis.

. N.B.. Abdominal CT used to detect intra-abdominal injury in hemodynamically stabletrauma pts. In hemodynamically un-stable pts, a FAST U/$ should be the initial test.. DPL Diagnostic peritoneal lavage is used in hemodynamically unstable pts if -ve FAST.

. N.B.. DIAPHRAGMATIC TRAUMA:

________________________. Blunt abdominal trauma -> Mild respiratory distress & Abnormal CXR.. Sudden ++ in intra-abdominal pressure -> Large radial tears in the diaphragm.. Rupture is more common on LEFT side bec. the right side is protected by the liver.. Dx -> CXR -> Hemi-diaphragmatic elevation.. Dx -> CXR -> Naso-gastric tube in the pulmonary cavity = Diaphragmatic hernia.. Dx -> CT is the next best step (to Confirm).. The small bowel may be present in the thoracic cavity.. Tx -> Surgical repair & exploration for other traumatic injuries.

. N.B.

. TRACHEO-BRONCHIAL RUPTURE:_____________________________. Due to rapid decceleration blunt chest trauma.. 1st manage the ABCs.. Dx -> CXR -> Persistent pneumothorax & pneumomediastinum despite chest tube placement !. Subcutaneous emphysema (Palpable crepitus below the skin).. The RIGHT MAIN BRONCHUS is the most commonly injured.. Dx -> High resolution CT scan (Confirm).. Tx -> Surgical repair.

. BLUNT ABDOMINAL TRAUMA MANAGEMENT:__________________________________________________________________________

. HEMODYNAMICALLY UN-STABLE PATIENT:_____________________________________-> Cervical spine immobilization.-> Intravenous hydration.-> FAST (Focused assessment with sonography for trauma).-> If FAST is +ve for blood & pt is still UNSTABLE AFTER A TRIAL OF FLUID RESUSCITATION,-> URGENT LAPAROTOMY with surgical repair is indicated.

. HEMODYNAMICALLY STABLE PATIENT:__________________________________-> CT scan abdomen with contrast (to detect the amount of bleeding & the site o


7/50

f injury).-> The surgeon can then select either laparotomy or admission & observation.

. MANAGEMENT OF BLUNT ABDOMINAL TRAUMA _______________________________________ . in HEMODYNAMICALLY UN-STABLE PT

__________________________________ | FAST EXAMINATION ________________ | ____________________________________________ | | | +ve inconclusive -ve | | | LAPAROTOMY Signs of

____________ _____ extra-abdominal hemorrhage (Pelvic/lon

g bone #) | ___YES_____________NO_____ || STABILIZE STABILIZE ANGIOGRAPHY & SPLINT then CTABDOMEN

* VASOMOTOR SHOCK:___________________. Hypotension & tachycardia in pts who are warm & flushed (Not pale & cold!).. Look for a H/O of medication use (penicillin allergy).. H/O of spinal anesthesia or exposure to allergen (bee stings).

* TRAUMA TO LOCALIZED SITES:_____________________________. All penetrating wounds with damage to internal organs will need to go to theOR.. If the case describes an object embedded in the pt, NEVER to remove it.

. Never remove it in the ER or at the scene of the accident (Only in the operating room).

* HEAD TRAUMA:_______________. "No" surgical intervention is needed for ... an asymptomatic head injury with a closed skull # (No overlying wound) alone.. The next step of management is to clean any lacerations.

. Surgery "Repair or craniotomy" is always done for ... COMMINUTED or DEPRESSED SKULL # even if the pt is asymptomatic !. Send the pt to the OR.

. For head trauma & loss of cosciousness. The 1st step of management is ordering a HEAD & NECK CT with "OUT" contrast.


8/50

. If the head CT & neurological exam are normal,. he can go home if someone can closely observe him over the next 24 hours.. i.e. wake him up frequently & watch for changes in mentation.. Give tetanus toxoid & prophylactic antibiotics to all pts with open skull #s.

* BASAL SKULL #:_________________. Ecchymosis around both eyes (Racoon eyes).. Ecchymosis behind the ear (Battle's sign).. Clear fluid drippling from the ear or nose (CSF leak).. CT scan of head & neck -> Basal skull #. "X-ray is a wrong answer".. A CSF leak will stop by itself & requires no specific management.. Prophylactic antibiotics are NOT indicated !!. Facial palsy may occur 2-3 days later due to neuroapraxia (Use Steroids).

* EPI-DURAL HEMATOMA:

______________________. Side head trauma & rupture of middle meningeal artery in the foramen spinosum.. H/O of head trauma & SUDDEN LOSS OF CONSCIOUSNESS.. Accumulation of blood in the potential space inbetween the cranium & dura matter.. Honeymoon period (The period when the pt immediately awakes & appears normal).. Pt typically has ipsilateral pupil dilatation due to oculomotor nerve compression.. Then the pt quickly deteriorates, so .. It is important to manage quickly.. Dx -> CT scan -> BICONVEX LENS shaped hematoma with or without midline deviation.

. Tx -> EMERGENCY CRANIOTOMY.. If the pt is treated, the prognosis is good.. If not, the prognosis is fatal within hours.

. Epidural hematoma results from rupture of middle meningeal artery,. higher arterial pressure can rapidly expand the hematoma -> Compress the temporal lobe.. Fluid resuscitation ++ the rate at which the epidural hematoma expanded.. Hypertension, bradycardia & respiratory depression (Cushing's reflex) = ++ ICP.. The uncus is the innermost part of the temporal lobe & herniated through thetentorium,

. leading to the following pressure effects:

. TRANS-TENTORIAL (UNCAL) HERNIATION:____________________________________________________________________________

. Compression of the contralateral crus cerebri against the tentorial edge:____________________________________________________________________________. Ipsilateral hemiparesis.

. Compression of the ipsilateral oculomotor nerve (CN 3) by the herniated uncus:________________________________________________________________________________

_. Loss of parasympathetic innervation causes mydriasis.. Loss of motor innervation causes ptosis & down-outwards gaze of the ipsilater


9/50

al pupil,. due to un-opposed trochlear (CN 5) & abducent (CN 6).

. Compression of the ipsilateral posterior cerebral artery:____________________________________________________________. causes ischemia of the visual cortex -> Contralateral homonymous hemianopia.

. Compression of the reticular formation:__________________________________________. Altered level of consciousness; coma.

* "S"UB-DURAL HEMATOMA:________________________. Low pressure bleeding from the "VENOUS SYSTEM".. Accumulation of blood in the subdural space between the dura & arachinoid membrane.. Head trauma with FLUCTUATING CONSCIOUSNESS i.e.. gradual headaches, memory loss, personality changes, dementia, cofusion & dro

wsiness.. Dx -> CT scan -> "S"EMILUNAR, CRESCENT shaped hematoma e' or e'out midline deviation.. Tx -> CONSERVATIVE management with STEROIDS.. Emergency craniotomy is done if there are lateralizing signs & midline displacement.

* DIFFUSE AXONAL INJURY:_________________________. Results from ACCELERATION-DECELERATION injuries to the head.. The pt will be deeply unconscious.. Dx -> CT -> Normal or diffuse small bleeds at the junctions of the grey & whi

te matter.. CT -> Numerous punctate hemorrhages.. Prognosis is terrible !. Surgery can't help.. Therapy is directed at preventing further injury from ++ ICT.

* ELEVATED INTRACRANIAL PRESSURE (++ ICP):___________________________________________. Briefly depressed consciousness after head trauma.. Improvement.. Progressive drowsiness.

. ++ ICT is a medical emergency.. GRADUAL DILATATION OF ONE PUPIL & DECREASING RESPONSIVENESS TO LIGHT is an imp. sign.. It indicates clot expansion on the ipsilateral hemisphere.. Dx -> Head CT -> Midline shift or dilated ventricles.. Don't think about performing a lumbar tap in any pt before getting a head CT1st !. If you perform a lumbar puncture on a person with ++ ICT, you'' herniate thebrain !. Tx -> Head elevation - Hyperventillation - Avoid fluid overload.. Tx -> Mannitol & furosemide (use very cautiously as they can reduce cerbral perfusion).. Tx -> sedation & hypothermia may lower oxygen demand.

. N.B. Lowering ICP is not the ultimate goal; preserving brain perfusion is.. Systemic hypotension or excessive cerebral vasoconstriction may be counterpro


10/50

ductive.. N.B. Steroids are good for cerebral edema 2ry to tumors & abscesses,. But they have no role in head trauma pts !

. N.B. Pts with mild to moderate traumatic brain injury:. can be discharged under the care of an adult if they have a NORMAL CT.

. The caretaker sh'd be given printed instructions detailing signs & symptoms that,. warrant immediate return to the hospital.__________________________________________________________________________________________

. ACUTE ABDOMEN:__________________________________

. 4 main causes -> Perforation - Obstruction - Inflammation/Infection - Ischemi

a.

. When is "SURGEY" the answer ?________________________________1. Peritonitis (Exclude primary peritonitis).2. Abdominal pain/tendrness + sepsis signs.3. Acute intestinal ischemia.4. Pneumoperitoneum.

. In all of the above cases, make sure pancreatitis is 1st ruled out !. N.B. Primary peritonitis is spontaneous inflammation with nephrosis in children.

. or .. An adult with ascites & mild abdominal pain (even there is fever & leukocytosis).

. When is "MEDICAL ttt" the answer ?_____________________________________1. Primary peritonitis.2. Pancreatitis.3. Cholangitis.4. Urinary stones (Look for stones on X-ray).5. Things that can mimic an acute abdomen: -> Lower lobe pneumonia (Look for infiltrate on CXR). -> Myocardial ischemia (Look for EKG changes).

-> Pulmonary embolism (Look for immobilized pt).6. Ruptured ovarian cyst.

. N.B.. Cholangitis is a GIT medical emergency & intervention with ERCP is the ttt ofchoice.

. NON-surgical causes of an acute abdomen:___________________________________________1. Myocardial infarction - acute pericarditis.2. Lower lobe pneumonia - pulmonary infarction.3. Hepatitis - GERD.4. DKA - Adrenal insuffeciency.

5. Pyelonephritis - Acute salpingitis.6. Sickle cell crisis.7. Acute porphyria.


11/50

. N.B.. Be sure to differentiate GERD from peptic ulcer perforation (surgical emergency).

* 1 * PERFORATION:___________________

___________________

(1) GASTRO-INTESTINAL PERFORATION:__________________________________. Acute abdominal pain that is sudden, severe, constant & generalized.. Pain is excruciating with any movement (may be blunted in elderly pts).. Most common causes of GIT perforations:(a) Diverticulitis: Elderly pt with lower abdominal pain & fever.

(b) Perforated peptic ulcer: Epigastric pain waking up the pt at night.(c) Chron's disease.

. Dx -> Supine & erect abdominal x-ray (free air under diaphragm).. Tx -> Nothing by mouth (NPO) & IV fluid hydration.

. Tx -> IV antibiotics such as flagyl & gentamycin.. Tx -> IV 2nd generation cephalosporins (Cefotetan or cefoxitin).. Tx -> Emergency surgery.

(2) ESOPHAGEAL PERFORATION:___________________________. Most common cause is IATROGENIC.. Pain in chest or upper abdomen.. Dysphagia or odynophagia.. S.C. emphysema shortly after endoscopy.. It is a surgical emergency.

. Dx -> GASTROGRAFFIN CONTRAST ESOPHAGOGRAM is the best (Do NOT use Barium xx).

* 2 * OBSTRUCTION:______________________________________. Severe colicky pain.. Absence of flatus or feces.. Nausea & vomiting.. Constant movement as the pt tries to find a comfort position.

. H/O of prior surgery (Think adhesions).. H/O of elderly pt with anemia, weight loss & melanotic stools (Think tumor).

. Dx -> CBC & ++ lactate level.. Dx -> Supine & erect abdominal X-ray: -> Dilated loops of bowel, absence of gas in rectum, bird's beak sign forvolvulus.. Tx -> NPO, (NG) suction & IV fluid hydration.. Consider Gastrograffin contrast study (Until perforation has been ruled out).

. Volvuls -> Perform procto-sigmoidoscop with rigid instrument. -> Leave the rectal tube in place.

-> Perform sigmoid resection for recurrent cases.

. Abdominal hernia -> Perform elective repair for all abdominal hernias.


12/50

-> except umbilical hernia in pts < 2 ys. -> except esophageal sliding hernia.

. All other obstructions -> Perform emergency surgery.. N.B.. In a pt with a hernia, immediate surgery is the answer if the case describes:

. fever, leukocytosis, constant pain & signs of peritoneal irritation (Strangulation).

. N.B.. Complete small bowel obstruction. Nausea - vomiting - Abdominal bloating - Dilated loops of bowel on abdominalx-ray.. Adhesions are the most common etiology.

. N.B.. SMALL BOWEL OBSTRUCTION:___________________________

. Colicky abdominal pain & vomiting.. No bowel movement or passing gas (Obstipation), abd. distension & diffuse tendernesss.. The contents of the vomitus are typically bilious in proximal SBO.. The contents of the vomitus are feculent with more distal obstructions.. Hyperactive bowel sounds due to peristaltic rush.. Dx -> Abd. x-ray -> DILATED BOWEL LOOPS with MULTIPLE AIR FLUID LEVELS.. Tx -> Complete bowel rest - Decompression e' nasogastric tube.. Tx -> Pain control - Fluid resuscitation.. Tx -> If no improvement -> Surgical intervention to avoid strangulation.. Strangulation signs (fever - tachycardia - leukocytosis - Metabolic acidosis).

. N.B.. Immediate surgical intervention is indicated for pts with intestinal obstruction who,. develop clinical or hemodynamic instability, fail to improve after conservative ttt,. or develop syms of strangulation (fever-tachycardia-leukocytosis-Metabolic acidosis).

* 3 * INFLAMMATION:________________________________________

. Causes (Acute diverticulitis - Acute pancreatitis - Acute appendicitis).. Gradual onset of constant abdominal pain that slowly builds up over several hours.. Initially ill defined pain that becomes localized to the site of inflammation.. Note that signs of peritoneal irritation are ABSENT in pancreatitis.

(1) ACUTE DIVERTICULITIS:__________________________. Acute abdominal pain in the LEFT LOWER QUADRANT (LLQ).. Middle age or older pt with fever, leukocytosis & peritoneal irritation in the LLQ.. Palpable tender mass in the LLQ.

. In women, think about fallopian tubes & ovaries as potential sources.. Dx -> CT -> Abscess & free air.. Never order contrast studies or endoscopy in acute phase.


13/50

. Tx -> If there is no peritoneal signs -> Manage as outpatient with antibiotics.. Localized peritoneal signs & abscess -> Admit pt - NPO - IV fluids - IV antibiotics.. Generalized peritonitis or perforation -> Emergency surgery.. Recurrent attacks of diverticulitis -> Elective surgery.

. N.B. When diagnosing acute diverticulitis,. don't forget to order a urine pregnancy test on all women of childbearing age.

. Complicated diverticulitis: Associated e' abscess, perforation, obstruction or fistula.. Fluid collection < 3cm -> IV antibiotics & observation.. Fluid collection > 3cm -> CT guided percutaneous drainage.. If no response within 5 days -> Surgery for drainage & debridement.

(2) ACUTE PANCREATITIS:________________________

. Alcoholic pt who develops an acute (over several hours) upper abdominal pain,. radiating to the back, with nausea & vomiting.. It may be edematous, hemorrhagic or suppurative (pancreatic abscess).. Late complications include pancreatic pseudocyst & chronic pancreatitis.. Dx -> Serum or urinary amylase or lipase (serum 12 - 48 hs, urinary 3rd - 6thday).. Dx -> CT if diagnosis is uncertain.. Tx -> NPO, NG suction & IV fluids.. N.B. Look out for the risk factors for acute pancreatitis:-> Alcoholism.-> Gall stones.-> Medications (Didanosine, pentamidine, Flagyl, Tetracycline, Thiazides & Furo

semide).-> Hypertriglyceridemia.-> Trauma.-> Post-ERCP.. N.B. COMPLICATIONS:

-> Abscess: . Often appears 10 days after onset with persistent fever & high WBC count. . Surgical drainage is the ttt.

-> Pseudocyst:

. Appears 5 weeks after initial symptoms. . when a collection of pancreatic juice causes anorexia, pain & a palpable mass. . If < 6 cm & present < 6 weeks -> OBSERVATION. . If > 6 cm or present > 6 weeks -> Percutaneous drainage or endoscopic drainage.

-> Chronic damage: . causes diabetes & steatorrhea. . Treat with insulin & pancreatic enzyme supplementation.

. N.B. The most common causes of acute pancreatitis are gallstones & alcohol use.

. Identifying the underlying cause can prevent recurrent pancreatitis.. ULTRASOUND is the preferred test to detect gall stones.. Stable pts sh'd undergo cholecystectomy for biliary pancreatitis prior to dis

charge.

(3) ACUTE APPENDICITIS:________________________. Begins with anorexia.. Followed by vague peri-umbilical pain.

. several hours later, it becomes sharp, severe, constant & localized to RLQ ofabdomen.. RIGHT LOWER QUADRANT PAIN.. Tenderness, guarding & rebound tendrness are found on the right & below the umbilicus.. Dx -> Fever, leukocytosis 10000 - 15000 with neutrophilia & immature forms.. Dx -> Reactive thrombocytosis..

Drainage of fluid into the dependent recto-vesical pouch.. Tender, fluctuant mass palpable only e' the tip of finger = recto-vesical pou

ch abscess. Fever, lukocytosis, painful defecation & diarrhea.. Tx -> Abscess drainage.

. N.B. CHRONIC ULCERATIVE COLITIS (CUC):_________________________________________. CUC is managed medically.. Elective surgery is done in the following conditions:-> Disease is present > 20 ys "High incidence of malignant degeneration".-> Multiple hospitalizations.-> Pt needs chronic high dose steroids or immunosuppressants.-> Toxic megacolon (Abd. pain - fever - leukocytosis - epigastric tendrness).

-> Massively distended transverse colon on X-rays with gas within the wall of the colon.

* 4 * ISCHEMIA:________________________________. Acute mesenteric ischemia in older pts.. H/O of arrhythmia (Af -> Absence of P waves with irregular rhythm).. Coronary artery disease.. Recent MI.. Severe acute onset abdominal pain that is out of proportion to exam.. Dx is clinical but look for acidosis & sepsis signs.

. If ischemia is suspected, don't w8 for lab findings (acidosis or ++ lactate),. Go straight to surgery or order angiography.. If diagnosis is during SURGERY -> Perform embolectomy & revascularization or


15/50

resection.. If diagnosis is during ANGIOGRAPHY -> Give vasodilators or thrombolysis.. Acute embolic mesenteric ischemia may progress to bowel infarction.

. N.B. INTRA-ABDOMINAL ABSCESS:________________________________. H/O of previous operation, trauma or intra-abdominal infection/inflammation.

. Abscesses can occur anywhere in the abdomen or retroperitoneum.. Dx -> CBC & contrast CT of abdomen or pelvis.. Tx -> Drain an intraabdominal abscess (either surgically or percutaneously).. Tx -> Give antibiotics to prevent spread of infection (Doesn't cure abscess).. Ex. PSOAS ABSCESS:. It is not an exclusive complication of appendicitis.. It may present alone (Absence of rebound tenderness of appendicitis !).. Presence of multiple furuncles on the inner thighs is a clue of septic focus!. Dx -> CT Abdomen.. Tx -> Surgical or percutaneous drainage.

. N.B. BOWEL ISCHEMIA:_______________________. One of the complications of abdominal aortic aneurysm repair surgery.. Due to inadequate colonic collateral arterial perfusion to the left & sigmoidcolon.. Due to loss of the inferior mesenteric artery during aortic graft placement.. Abdominal pain (Dull pain over ischemic bowel) & bloody diarrhea (Hematochezia).. Fever & leukocytosis.. Colonoscopy -> Discrete segment of cyanotic & ulcerated bowel.. Prevention -> Checking sigmoid colon perfusion following graft placement.

. SURGICAL JAUNDICE:________________________________________* OBSTRUCTIVE JAUNDICE CAUSED BY STONES:

_________________________________________. Obese, fecund woman in her 40s.. Recurrent episodes of abdominal pain.. High alkaline phosphatase.. Dilated ducts on sonogram.. Non-dilated gall bladder full of stones.

. Dx -> Abdominal U/$.. Dx -> Confirm e' endoscopic ultrasound (EU$).. Dx -> Confirm e' Magnetic resonance cholangiopancreatography (MRCP).. Tx -> Perform Endoscopic retrograde cholangiopancreatography (ERCP).. Tx -> Cholecystectomy sh'd follow ERCP.

. N.B. ERCP & EU$ are never the 1st step in diagnosis.. N.B. ERCP is mostly a management step on exam.

* OBSTRUCTIVE JAUNDICE CAUSED BY TUMOR:________________________________________. Progressive symptoms in the preceeding weeks & weight loss.. Adenocarcinoma at the head of pancreas.

. Adenocarcinoma at the ampulla of Vater.. Cholangiocarcinoma arising in the common bile duct itself.. Dx -> Abdominal U/$.


16/50

. Dx -> CT scan.. Dx -> For lesions on CT -> Obtain a tissue diagnosis via EU$.. Dx -> If no lesions on CT -> Order MRCP.. MRCP -> will show the ampullary or common bile duct tumors not seen on CT scan.. Obtain tissue diagnosis via ERCP.. Tx -> Surgical resection.

. GALL STONES:______________________________(1) BILIARY COLIC:

___________________. TEMPORARY occlusion of the CYSTIC DUCT.. Colicky pain in the upper right quadrant RUQ.. Radiating to the right shoulder & back.. Often triggered by fatty food.

. Episodes are brief (20 mins).. No signs of peritoneal irritation or systemic signs.. Dx -> U/$.. Tx -> Elective cholecystectomy.

. N.B. Ingestion of a fatty meal causes the gall bladder to contract.. so .. it presses the gall stones against the cystic duct opening,. increasing the intra gall bladder pressure causing VISCUS DISTENSION & colicky pain.. Subsequent gall bladder relaxation alows the stone to fall back from the duct,. causin the pain to resolve completely.. Biliary colic pain may be referred to right shoulder.

. N.B. Pain of biliary colic is distinguished from that of acute cholecystitisby:. its intermittent nature & relation to meals as well as absence of fever.(2) ACUTE CHOLECYSTITIS:

_________________________. PERSISTENT occlusion of the CYSTIC DUCT.. Caused by a stone.. Constant pain.. Fver, leukocytosis & peritoneal irritation in the RUQ.. Dx -> U/$ (Gall stones - Thick walled gall bladder - Pericholecystic fluid).

. Tx -> NG suction - NPO - IV fluids - IV antibiotics.. Tx -> Followed by elective cholecystectomy after 6 - 12 wks.. Tx -> Emergency cholecystectomy is needed if there is:. generalized peritonitis or ephysematous cholecystitis (i.e. perforation or gangrene).(3) ACUTE ASCENDING CHOLANGITIS:

_________________________________. Obstruction of the COMMON BILE DUCT causes obstruction & ASCENDING INFECTION.. High fever & very high WBC count.. High levels of alkaline phosphatase.. High levels of total & DIRECT bilirubin.. Mild elevation of transaminases.

. Tx -> IV antibiotics.. Tx -> Emergency decompression of the common bile duct is life saving !. Decompression by ERCP or PTC (Percutaneous transhepatic cholangiogram) or sur

gery.. Tx -> Cholecystectomy must follow.

. N.B.. A pregnancy test sh'd be performed in any woman of childbearing period age before,. ordering diagnostic tests such as x-rays or computed tomography scans.

. PRE-OPERATIVE & POST-OPERATIVE CARE:____________________________________________________________________________* PRE-OPERATIVE ASSESSMENT:

____________________________

{1} CARDIAC RISK:__________________. Ejection fraction < 35 % -> Prohibits non-cardiac surgery.

. JVD (sign of CHF) -> Give ACEIs, BB, Digitalis & Diuretics prior to surgery.. Recent MI -> Defer surgery for 6 months post MI.. Severe progressive angina -> Cardiac catheterization for coronary revascularization.

{2} PULMONARY RISK:____________________. Smoking (Compromised ventillation = High pCO2 & FEV1 < 1.5): -> Order PFTs to evaluate for FEV1. -> If FEV1 is abnormal -> Obtain ABG. -> Cessation of smoking 8 weeks prior to surgery.

{3} HEPATIC RISK:

__________________. Bilirubin > 2 mg/dl.. Prothrombin time > 16.. Serum albumin < 3.. Encephalopathy.

-> 40 % mortality with any single risk factors.-> 80 % mortality if 3 or more risk factors are present.{4} NUTRITIONAL RISK:

______________________. Loss of 20 % of body weight over several months.

. Serum albumin < 3.. Anergy to skin antignes.. Serum transferrin < 200 mg/dl.

-> Provide 5-10 days of nutritional supplements (preferrably via gut) before surgery.. N.B. DIABETIC COMA is an ABSOLUTE contraindication to surgery.. 1st stabilize diabetes.. Rehydrate & normalize acidosis prior to surgery.

. N.B.

. If a pt presents with an acute abdomen due to perforation of hollow abdominalviscus,. (Rebound tendrness & subdiaphragmatic free intraperitoneal air on abdominal x


18/50

-ray),. the pt will require IMMEDIATE LAPARATOMY !. Pre-operative naso-gastric tube decompression is a must.. Give IV fluids & IV antibiotics.

. In a pt on warfarin due to Af, Warfarin induced anti-coagulation must be reversed !

. Bec. if it isn't reversed, it will lead to intra & postoperative bleeding complications. The most rapid mean of normalizing PT: restoration of vit K dependent clotting factors.. through infusion of FRESH FROZEN PLASMA.

. POST-OPERATIVE COMPLICATIONS & MANAGEMENT:________________________________________________________________________________________{1} MALIGNANT HYPERTHERMIA (Exceeding 104 F):

______________________________________________. Shortly after the onset of the anesthetic (Halothane or succinyl choline).. Tx -> IV DANTROLENE, 100% oxygen, Acidosis correction & cooling blankets.. Watch for development of myoglobinuria.

{2} BACTEREMIA (Exceeding 104 F):__________________________________. Within 30-45 mins of invasive procedures (UTI instrumentation).. 3 successive blood cultures.. Start empiric antibiotics.

{3} POST-OPERATIVE FEVER (101 - 103 F):________________________________________

* ATELECTASIS (Day 1):

________________________-> Lobar or segmental collapse of the lung -> -- lung volume.-> Due to impaired cough & shallow breathing.-> Due to accumulation of pharyngeal secretions.-> Due to the tongue prolapsing posteriorly into the pharynx.-> Due to airway tissue edema or residual anesthetic effects.-> Causes significant ventillation - perfusion mis-match -> hypoxemia & ++ breathing work-> Atelectasis is MOST SEVERE at the SECOND POSTOPERATIVE DAY NIGHT.-> As a compensation for hypoxia -> Hyperventilation -> Respiratory alkalosis &

-- pCO2.-> Ex -> pH 7.49, pO2 70 mmHg, pCO2 50 mmHg.-> Prevention: Breathing exercises - Incentive spirometry - Forced expiratory techniques.

. N.B.. Moving from supine to sitting position ++ the functional residual capacity FRC by 25%.. ++ FRC prevents post-operative atelectasis.* "WIND" PNEUMONIA (Day 3):

____________________________-> CXR -> Infiltrate.

-> Sputum culture.-> Antibiotics (Hospital acquired pneumonia).-> Prevention : Post-operative breathing exercises & incentive spirometry.


19/50

* "WATER" URINARY TRACT INFECTION (Day 3):

___________________________________________-> Urinalysis & urinary culture.-> Antibiotics.

* "WALKING" DEEP VENOUS THROMBOPHLEBITIS (Day 5):

__________________________________________________-> Doppler U/$ of deep veins of legs & pelvis.-> Anticoagulation.

* "WOUND" WOUND INFECTION (Day 7):___________________________________-> Antibiotics if only cellulitis.-> Incision & drainage if abscess is present.

* DEEP ABSCESSES (SUBPHRENIC - PELVIC - SUBHEPATIC) (Day 10 - 15):___________________________________________________________________-> CT scan of the appropriate body cavity is diagnostic.

-> Percutaneous radiologically guided drainage is therapeutic.

{4} PERIOPERATIVE MYOCARDIAL INFARCTION:_________________________________________. Precipitated by hypotension when intraoperative.. Postoperative MI seldom presents with chest pain..

Azotemia ( ++ BUN/Creatinine ratio > 20:1) = Acute Pre-renal failure from HYPOVOLEMIA !. Urinary catheter obstruction should be ruled out 1st.. Next step is an IV FLUID CHALLENGE.

. N.B.. Post-operative ileus:

________________________. An ileus is a functional defect in the bowel motility without physical obstru

ction.. Following most abdominal surgeries.. Nausea, vomiting, abdominal distension, failure to pass flatus or stools.. Hypoactive or absent bowel sounds.. In contrast (Mechanical obstruction e.g. adehsions cause "HYPERactive" bowelsounds).. Causes of ileus:-> ++ splanchnic nerve sympathetic tone following violation of the peritoneum.-> Local release of inflammatory mediators.-> Postoperative narcotic (opiate) analgesics e.g Morphine causes disordered peristalsis.

. N.B.

. Post-operative DVT:______________________. DVT occurs due to Virchow triad (Stasis - endothelial injury - Hypercoagulability).. Major surgery is a significant risk factor.. Pts sh'd be ttt with LMW HEPARIN acutely & warfarin for several months.. Stable pts can be ttt with anticoagulation as early as 48 - 72 hours after surgery.

. N.B.. Transfusion reactions:_________________________

. occur acutely during or immediately following transfusion of blood products.. They are immune mediated;. preformed host antibody reacts with antigens on transfused blood products,. causing the release of inflammatory mediators & complement activation.. They may be HEMOLYTIC -> Severe reaction that may cause death.. or NON-HEMOLYTIC -> Dose dependent self limited reaction with fever & rigors.

. N.B.. CATHETER (CENTRAL LINE) ASSOCIATED INFECTIONS:_________________________________________________. Intra-venous catheters are one of the most common causes of nosocomial infections.. Femoral central venous catheters carry a higher risk of bacteremia than subcl

avian cath. IV catheter infections are mostly caused by cutaneous organisms such as STAPHYLOCOCCI.


21/50

. Femoral catheters may also cause gram -ve bacteremia.

. N.B. Post-operative ACUTE ADRENAL INSUFFECIENCY:___________________________________________________. Acute onset of nausea, vomiting, abdominal pain, hypoglycemia & hypotension.. follows a stressful event e.g. surgical procedure..

* OMPHALOCELE:_______________. The umbilical cord goes to the defect.. The defect has a thin membrane (one can see normal looking bowel & little liver slice).

. Tx -> Small defects -> Close small defects primarily.. Tx -> large defects -> Silastic "silo" to protect the bowel.. Manual replacement of the bowel daily until complete closure (in about 1 week).. Give parenteral nutrition (The bowel will not work in gastrochisis).

{5} EXSTROPHY OF THE URINARY BLADDER:______________________________________. This is an abdominal wall defect over te pubis.. Refer to a specialized center offering surgical repair in 1st 1-2 days of life.. Do NOT delay surgery.

{6} INTESTINAL ATRESIA:________________________. Like annular pancreas, it presents with green vomiting.. But, instead of double-bubble sign, there are multiple air-fluid levels in the abdomen.. There is no need to suspect other congenital anomalies,. because this condition results from a vascular accident in utero !

Thoracic outlet $ causes vascular symptoms only with-OUT neurological signs.

. Dx -> Angiography.. Tx -> Bypass surgery.

{2} AORTIC ANEURYSM:_____________________. Size & symptoms are key to management of "ABDOMINAL" aortic aneurysm:-> Aneurysms < 5cm -> Observe with serial annual imaging.-> Aneurysms > 5cm -> Elective surgical repair.

. More urgent surgery is needed if:-> A TENDER AAA will rupture within a day or two requiring urgent repair.-> Excruciating back pain in a pt e' large AAA means that,

. the aneurysm is already leaking, necessitating emergency surgery.

. N.B. The following contributes to the development of "THORACIC" aortic aneurysm:-> Chronic hypertension.-> Hyperlipidemia.-> Smoking.-> Marfan $.-> Untreated tertiary $yphilis.

. N.B. The most imp. modifiable risk to prevent worsening of existing aneurysmsis:

-> UNCONTROLLED HYPERTENSION.

. N.B. Asymptomatic lesions -> BLOOD PRESSURE MANAGEMENT is the most important.. N.B. Symptomatic lesions (including active dissection) -> Surgical intervention.. (Look for sudden onset tearing pain in the back).

{3} ARTERIOSCLEROTIC OCCLUSIVE DISEASE OF THE LOWER EXTREMETIES:_________________________________________________________________. Pain in the legs on exercise that is relieved by rest (intermittent claudication).

. If the claudication doesn't affect the pt's life style -> No intervention isneeded.. The only management indicated is CESSATION OF SMOKING & THE USE OF CILOSTAZOL


33/50

.

. If the pain is more severe,. Dx -> Doppler studies (Pressure gradient ABI < 0.9).. Dx -> Arterigram to identify stenosis.

. If there is DISABLING symptoms (Affect work or daily life activity),

. or there is impending ischemia to the extremity,. Tx -> SURGERY (Angioplasty & stenting for stenotic segments).. More extensive disease requires bypass grafts or sequential stents.

. N.B. PAIN AT REST indicates END STAGE DISEASE (Pt complains of calf pain at night).

. N.B. VVVVVVVVVVVVVVVVV. imp.. The 1st step in evaluating a pt with suspected peripheral artery disease (PAD) is:. to obtain an ANKLE-BRACHIAL INDEX (ABI) to confirm the diagnosis.

. Aspirin & cilostazol are antiplatelet agents that can be given after confirming PAD.. They are not given upon clinical suspicion !. Pts with significant symptoms & NORMAL ABI may have MILD diesase at rest.. They sh'd undergo EXERCISE TESTING with pre & post exercise ABI measurment toconfirm.

. ABI (1.0 - 1.3) -> Normal.. ABI < 0.9 -> > 50 % occlusion of a major vessel.. ABI < 0.4 -> Limb ischemia.

. N.B. ISCHEMIA REPERFUSION $YNDROME:

. A form of compartment $.. Extremeties subjected to at least 4-6 hours of ischemia,. suffer from intracellular & interstitial edema upon reperfusion (SOFT TISSUESWELLING).. When edema causes the pressure within a muscular fascial compartment to rise> 30 mmHg. compartment $ occurs leading to further ischemic injury to the confined tissue.

. N.B. COMPARTMENT $ 5 "P"s:____________________________. May be caused by direct trauma (Hemorrhage), prolonged compression of an extr

emity.. May be caused after revascularization of an acutely ischemic limb.. Muscles of extremity are encased in fascial compartments preventing tissue expansion.. The ++ pressure interferes with perfusion leading to muscle necrosis.. Pressure > 30 mmHg leads to cessation of blood flow through capillaries.. Tx -> EMERGENT FASCIOTOMY.-> Pain . Earlest symptom. . ++ by passive stretch of the muscles in the affected compartment.

-> Paresthesia

. Burning or tingling sensation. . occurs in the distribution of the affected peripheral nerve.


34/50

-> Pallor . of the overlying skin . result from tense swelling & compromised perfusion.-> Pulselessness . Late finding. . Presence of a pulse on exam does NOT rule out compartment $.

-> Paresis/Paralysis . Late finding. . resilt from nerve & muscle ischemia & necrosis.

. N.B. ESCHAR !. Eschar is a firm necrotic tissue formed on on exposed tissue following burn wounds.. When eschar occurs circumferentially on an extremity,. it restricts the outward expansion of the compartment as edema follows burn.. Interstitial pressure increases -> compromise vascular flow to the limb.

. Deep pain out of proportion to injury, pulselessness, paresthesia, cyanaosis& pallor.. Tx -> Escharotomy.

. N.B. Compartment $ 2ry to SUPRA-CONDYLAR # of humerus:. 2ry to fall on out-stretched hand.. Due to ++ pressure in a limited space.. Pain, pallor, pulselessness, paralysis & presthesia.. Tx -> Immediate fasciotomy.. N.B. VOLKMANN's ISCHEMIC CONTRACTURE:. is the final sequel of compartment $ (The dead muscle is replaced by fibroustissue).

{4} ARTERIAL EMBOLIZATION OF THE EXTREMETIES:______________________________________________. H/O of Af or recent MI.. Sudden onset painful, pale, cold, pulseless, paresthetic & paralytic lower extremity.. Dx -> Doppler studies to locate the obstruction.. Tx -> Thrombolytics (if early) & Embolectomy (if later) with fasciotomy.

. N.B. LERICHE $YNDROME = AORTO-ILIAC OCCLUSION:

_________________________________________________. Arterial occlusion at the bifurcation of the aorta in the common iliac arteries.. Triad of bilateral hip, thigh & buttock claudication, impotences &. symmetric atrophy of the bilateral lower extremeties due to chronic ischemia.. Absence of impotence excludes the condition.

. N.B. SPINAL CORD ISCHEMIA:

_____________________________. Follows aortic vascular surgery due to anterior spinal artery $.. The spinal cord derives its blood supply from the:. anterior spinal artery & 2 posterior spinal arteries originating from vertebr

al artery.. Presents with flaccid paralysis, bowel/bladder dysfunction, sexual dysfunction.


35/50

. Possible hypotension & loss of deep tendon reflexes.. Spasticity & hyperreflexia develop over days to weeks.. Vibratory & proprioceptive sensation is preserved as posterior circulation ispreserved. Dx -> Emergent MRI.. Tx -> Supportive care & lumbar drains to reduce spinal pressure.

__________________________________________________________________________________________

. MISCELLANEOUS TOPICS:________________________________________________. GASTRIC OUTLET OBSTRUCTION:

______________________________. Can be caused by many diseases causing mechanical obstruction e.g.. Gastric malignancy - Peptic ulcer disease - Chrons dis - Strictures e' pylori

c stenosis. Strictures 2ry to ingestion of caustics.. Characterized by early satiety, nausea, non-bilious vomiting & weight loss.

. P/E -> ABDOMINAL SUCCUSSION SPLASH, elicited by placing the stethoscope,. over the upper abdomen & rocking the pt back & forth at the hips,. Retained gastric material > 3 hours after a meal will generate a splash sound,. indicating the presence of a hollow viscus filled with both fluids & gas.. In a pt with a H/O of acid ingestion, pyloric stricture is the most likely cause.. H/O of a recent acid ingestion is a risk factor of developing pyloric strictu

re.. Acid ingestion causes fibrosis 6-12 weeks after the resolution of acute injury.. Dx -> Upper endoscopy.. Tx -> Surgery.

. TOTAL BODY BURN & SYSTEMIC INFLAMMATORY RESPONSE $:______________________________________________________. Systemic inflammation & tissue injury.. Burn -> Dysregulated host response,. Massive uncontrolled release of proinflammatory substances -> extensive tissu

e damage.. This is known as systemic inflammatory response $yndrome:-> Temperature -> > 38.5 c (101.3 F) or < 35 c (95 F) !!!!!-> Pulse -> > 90/min.-> Respirations -> > 20/min.-> WBC > 12000 or < 4000 or > 10 % bands !!!!. SIR$ can follow pancreatitis, autoimmiune dis, vasculitis & burns.. Sepsis (SIRS e' a known infection) is considered severe when there is end organ failure. Oliguria - Hypotension (SBP < 90mmHg) - Thrombocytopenia (PLT < 80000).. Metabolic acidosis - Hypoxemia.

. Hyperglycemia occur due to insulin resistance.. Muscle wasting & protein loss & Hyperthermia.. Sepsis with septic shock may occur in the 1st week post-burn.


36/50

. Main causes of sepsis are pneumonia & wound infections (Staph aureus & Pseudomonas).

. Criteria indicating sepsis -> Leukocytosis - Thrombocytopenia - Mild hypothermia < 36.. Tachypnea & tachycardia due to associated pneumonia.. Worsening hyperglycemia due to worsening insulin resistance.

. Bottom line:. In pts with severe significant total body surface areas burns,. The major cause of morbidity & mortality is HYPOVOLEMIC SHOCK.

. In case of adequate initial fluid resuscitation,. Bacterial infection (Bronchopneumonia or burn wound infection) -> Sepsis & septic shock

. INTRA-PERITONEAL RUPTURE OF THE BLADDER:___________________________________________

. Intra-abdominal pathology causing shoulder pain = Subdiaphragmatic peritonitis.. Among the possible blunt traumatic bladder injuries,. Only an INTRA-PERITONEAL RUPTURE OF THE (BLADDER DOME) -> CHEMICAL PERITONITIS.. The dome of the bladder is the only region covered by peritoneum.. Pain could be transferred to the ipsilateral shoulder because,. Phrenic nerve originates from C3 to C5 spinal nerves mediating sensation forshoulders.

. INTRA-ABDOMINAL MALIGNANCY (CANCER PANCREAS):________________________________________________

. Day time fatigue, anorexia, significant weight loss.. Visceral type abdominal pain interfering with sleep.. Constant eigastric pain radiating to the back, weight loss & jaundice.. Migratory thrombophlebitis is a classic association.. N.B.. A peptic duodenal ulcer causes periodic epigastric pain relieved by meals.

. PILO-NIDAL SINUS:____________________. Acute pain & swelling of the midline sacro-coccygeal skin & subcutaneous tiss

ues.. Due to infection of a dermal sinus tract originating over the coccyx.

. RIB #:_________. Pain relief is the prime objective in management of rib #.. As it allow proper ventillation & prevent atelectasis & pneumonia.

. TETANUS PROPHYLAXIS:______________________________________________

. Un-immunized, uncertain or < 3 tetanus toxoid doses:_______________________________________________________


37/50

. Minor clean wound -> Tetanus toxoid only.. Severe or dirty wound -> Tetanus toxoid & tetanus immunoglobulins.

. > 3 tetanus toxoid doses:____________________________. Minor & clean wound -> None.. Severe or dirty wound -> Tetanus toxoid if latest boster given > 5 years ago.

. N.B. Tetanus-diphtheria toxoid sh'd be given to individuals with severe or dirty wounds. who received a booster > 5ys ago. & those with minor clean wounds who received a booster dose > 10 ys ago.

. N.B. Tetanus immune globulin sh'd be given to any individual with severe dirty wound. & unclear or incomplete immunization history.

. CO CARBON MONOXIDE POISONING:

________________________________. H/O of smoke inhalation.. CO is a tasteless, colorless & odorless gas.. It has affinity 200 times more than O2 for hemoglobin.. Confusion, wheezes, headache, nausea, dyspnea, malaise, altered mentation, dizziness.. If severe -> Seizure, coma, syncope, heart failure & arrhythmias.. Bright cherry lips can be seen but not specific.. Dx -> ++ Carboxyhemoglobin level > 3 % in non-smokers & > 15 % in smokers.. Tx -> 100 % OXYGEN NON-BREATHER FACE MASK.

. BREAST PROBLEMS:____________________________________

. 1 . INTRA-DUCTAL PAPILLOMA:______________________________. Benign breast disease.. Most common in peri-menopausal women.. Intermittent BLOODY discharge from one nipple.. Most intraductal papillomas are situated beneath the areola.

. Difficult to palpate on physical examination due to their small sizes (< 2 mm).. Soft in consistency.. U/$ will be normal because it can detect masses only greater than 1 cm in diameter.

. 2 . FIBRO-CYSTIC DISEASE:____________________________. Very common in pre-menopausal women.. Bilateral breast pain.. Associated with cystic changes of the breast.. Benign condition.. Symptoms vary cyclically with the menstrual cycle.

. P/E -> Lumpiness of the breast.

. 3 . FIBRO-ADENOMA:


38/50

_____________________. Solitary breast lesion.. Painless, firm, mobile breast lump.. Average size about 2 cm.. Women ages 15 - 25 ys.. Benign condition.. Do NOT change with menstrual cycle.

. 4 . DUCTAL CARCINOMA IN-SITU:________________________________. Post-menopausal women.. Incidental finding on mammography.. Nipple discharge & breast mass are the most common complaints.. It is a HISTOLOGICAL diagnosis.

. 5 . INFLAMMATORY BREAST CARCINOMA:_____________________________________. Brawny edematous cutaneous plaque.. "P'eau d'orange" orange peel appearance overlying a breast mass.

. It is an aggressive tumor.. 1/4 of the pts have metastatic disease at the time of presentation.. Most pts present with axillary lymphadenopathy.. Spontaneous nipple discharge is a sign of breast cancer.. Nipple discharge in a non-lactating woman sh'd always raise suspicion for cancer,. spontaneous, unilateral, localized to single duct, bloody discharge in pt > 40 ys old.. Mass association is an imp. sign of malignancy.. Clinicalyy, you can't differentiate it from an inflammatory process (breast abscess).. A BIOPSY FOR HISTOLOGY IS THE MAIN STAY OF DIAGNOSIS !

. PALPABLE BREAST MASS EVALUATION:

___________________________________

PALPABLE BREAST MASS ______________________ | ________________________________ | | < 30 ys > 30 ys | | ULTRASONOGRAM ONLY MAMMOGRAM & ULTRASONOGRAM
